DETAILED DESCRIPTION

With reference to FIGS. 1-3, a self-defense stick according to a preferred embodiment of the present invention comprises: a body 10, an air inflation portion 20, and a warning portion 30.

The body 10 includes a grip 11 and a connection rod 12 connected with the grip 11, wherein the connection rod 12 includes a first fixing segment 121 and a second fixing segment 122, and the grip 11 includes a spray outlet 112 and a first button 111, wherein the grip 11 is configured to accommodate anti-riot agent.

The body 10 is made of highly rigid materials, such as aluminum alloy, steel, engineering plastic, or carbon fiber. The grip 11 is one-piece formed (not shown) or is removably connected with the connection rod 12, for example, the grip 11 is screwed with the connection rod 12 by ways of threads, thus connecting or detaching the grip 11 with or from the connection rod 12. Furthermore, the grip 11 and the connection rod 12 are connected at 90 degrees.

The grip 11 accommodates the anti-riot agent which is any one of pepper spray, lachrymatory agent, stimulant, and lachrymatory spray.

The grip 11 includes the spray outlet 112 and the first button 111, such that the first button 111 is pressed to spray the anti-riot agent out of the spray outlet 112.

The grip 11 is removably connected with the connection rod 12, wherein the grip 11 is screwed with the connection rod 12 by using the threads so as to remove the grip 11 from the connection rod 12 and to feed the anti-riot agent.

The air inflation portion 20 includes a column 21 connected with the first fixing segment 121 of the connection rod 12, a drive peg 22, and an air nozzle 23 defined on an outer wall of the column 21.

The column 21 is made of the highly rigid materials, such as aluminum alloy, steel, engineering plastic, or carbon fiber, wherein the column 21 is formed as a cylinder of an independent inflator, and the cylinder has a piston (not shown) connected with the drive peg 22, when the drive peg 22 is pumped with respect to the column 21, airs are pumped out of the air nozzle 23.

The column 21 has a screwing section configured to screw with a threaded section of the first fixing segment 121, thus removably connecting with the connection rod 12.

In another embodiment, the column 21 is engaged or locked with the first fixing segment 121, thus removably connecting with the connection rod 12.

After removing the column 21 from the first fixing segment 121, the air inflation portion 20 is separated from the body 10 so as to form the independent inflator. Preferably, the drive peg 22 has a coupling segment 221 formed on an end thereof and coupled with the connection rod 12 so that the connection rod 12 is grasped when pumping the air, wherein the coupling segment 221 has threads screwed with the first fixing segment 121 of the connection rod 12.

The air inflation portion 20 further includes a nut 222 mounted in an opening of the column 21, and the nut 222 has a through hole (not shown) configured to slidably accommodate the drive peg 22, thus pumping the airs smoothly.

The warning portion 30 includes a cylinder 31 and a second button 32, wherein the cylinder 31 is in connection with the second segment 122, and the warning portion 30 includes an alarm (not shown) and at least one battery/cell (not shown), such that after pressing the second button 32, the alarm of the warning portion 30 is driven to make warning noises.

The warning portion 30 further includes an electric circuit, a buzzer, and the at least one battery/cell which are accommodated in the warning portion 30. The warning portion 30 further includes a power outlet (not shown) formed in a universal serial bus (USB) socket or a Type-C socket, wherein the at least one battery/cell is electrically connected with and supplies power to a mobile device (not shown).

The cylinder 31 is removably screwed with the first fixing segment 122 by ways of threads so as to detach from the warning portion 30, hence the cylinder 31 is used as the alarm or illuminates lights.

Thereby, the self-defense stick is capable of inflating the airs, spraying the anti-riot agent, and making the warming noises.

Preferably, the cylinder 31 has an alert aperture 33 configured to send the warning noises, when the alarm makes the warning noises.

The warning portion 30 further includes a lamp 34 and a third button 32A which is pressed to start the lamp 34 to emit the lights.

The self-defense stick further comprises a hit portion 50 connected with an end of the air inflation portion 20, and the hit portion 50 includes a conical post 51, thus hitting an object effectively.

The self-defense stick further comprises a hanger 40 including a hook 41, and the hanger 40 is connected with the body 10. The hook 41 is configured to hook the self-defense stick on a user's pants or belt.

The connection rod 12 has at least one threaded orifice 124 configured to screw with a screw 43 of the hanger 40. The hanger 40 includes a receiving orifice 42 configured to receive the screw 43. In another embodiment, multiple threaded orifices 124 are formed on each of two sides of the connection rod 12, such that the hanger 40 is fixed on different positions of the body 10 based on using requirements.

Referring to FIGS. 4 and 5, the coupling segment 221 is coupled in the first fixing segment 121 so that the end of the drive peg 22 is connected with the connection rod 12. Thereby, when inflating the airs, the grip 11 of the body 10 is grasped easily. Preferably, the coupling segment 221 is connected with the first fixing segment 121 so that the air inflation portion 20 is connected with the body 10 strongly.

When inflating the airs, the air nozzle 23 is coupled with an air inlet of a vehicle. Alternatively, an air hose 232 is connected into the vehicle to inflate the airs.

As shown in FIG. 6, when grasping the grip 11 with a user's palm, a thumb of the user touches and presses the first button 111 so as to spray the anti-riot agent to an attacker via the spray outlet 112 of the grip 11, thus obtaining defense.

The grip 11 is formed in a pepper spray having a threaded section so as to connect with the connection rod 12.

As illustrated in FIG. 7, the second button 32 is pressed to trigger the alarm to make the warning noise loudly from the alert aperture 33, thus frightening gangsters.

With reference to FIG. 8, the hook 41 of the hanger 40 is hung on user's waist, and the hanger 40 is changeably moved beside the body 10 based on the using requirements.

Referring to FIG. 9, the third button 32A is pressed to start the lamp 34 to emit the lights.

Preferably, the warning portion 30 is detachable from the connection rod 12 to be used as a flashlight independently.

As various changes could be made in the above constructions, products, and methods without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
